Jan 8, 2013 · Image blurring is achieved by convolving the image with a low-pass filter kernel. It is useful for removing noise. It actually removes high frequency content (eg: noise, edges) from the image.

Image filtering is a process of averaging the pixel values so as to alter the shade, brightness, contrast etc. of the original image. By applying a low pass filter, we can remove any noise in the image. High pass filters help in detecting the edges. The OpenCV library provides cv2.filter2D() function. It performs convolution of the original ...
